Curriculum Chapters
Integer Exponents & Scientific Notation
Apply product, quotient, and power rules; handle zero and negative exponents; write numbers in scientific notation.
Square Roots, Cube Roots & Irrationals
Evaluate perfect square and cube roots, approximate irrationals, and solve equations of the form x² = p.
Linear Equations in One Variable
Solve multi-step equations, equations with variables on both sides, and decide one, none, or infinite solutions.
Systems of Linear Equations
Solve two equations in two unknowns by graphing, substitution, and elimination, and model real-world systems.
Functions
Define a function, use the vertical-line test, evaluate f(x), and translate between four representations.
Linear Functions & Slope
Find slope from two points, write and graph y = mx + b, and model situations with a linear function.
Transformations & Congruence
Translate, reflect, and rotate figures; describe sequences of transformations; use congruence to find unknowns.
Similarity & Dilations
Perform dilations, decide similarity, use the AA criterion, and solve real-world problems with similar figures.
The Pythagorean Theorem
State the theorem and its converse, find missing sides, compute distance on the plane, and apply it in 3-D.
Bivariate Data
Build scatter plots, describe association, fit a line, make predictions, and read two-way frequency tables.
